For the 100th episode of the Expecting and Empowered podcast, Amy is bringing on a powerhouse in the world of reproductive nutrition. Today’s guest is McKenzie Caldwell, MPH, RDN - a registered dietitian specializing in nutrition for fertility, pregnancy, postpartum, and overall reproductive health. As the founder of Feed Your Zest Nutrition & Wellness, McKenzie supports women navigating PCOS, endometriosis, gestational diabetes, lactation concerns, and more, helping them feel fully nourished through every stage of their journey.

In this milestone conversation, McKenzie explains how nutrition directly impacts fertility for both women and men. She highlights the key distinctions between supporting preconception health and managing infertility, and shares what she wishes every listener knew about fueling their body before trying to conceive. The duo also discusses using nutrition to help regulate the menstrual cycle, restore depleted nutrient stores after pregnancy and breastfeeding, and understand the very real impact of under-eating on hormone health, cycle regularity, and the ability to get pregnant again. McKenzie shares why she dislikes “bounce-back culture” and gives ways to nourish the body through all seasons of motherhood. If you are struggling with nausea during pregnancy, McKenzie has great tips of foods to include in your diet to help alleviate it, and why fiber is currently such a popular macronutrient - for good reason! This 100th episode is packed with encouragement, expert advice, and empowering guidance for women navigating nutrition through fertility journeys, pregnancy, postpartum, and beyond!
